A website that provides U.S. consumers with a free annual credit report
appears to have been the source used by hackers to download those of
celebrities including BeyoncA(c) and government officials including
Federal Bureau of Investigation Director Robert Mueller.

On Tuesday, a website called "Exposed.su" published Social Security
Numbers, previous addresses, and birthdates of a range of well-known
people, including former Secretary of State Hillary Clinton, Jay Z,
Michelle Obama, Vice President Joe Biden, Hulk Hogan, Donald Trump and
U.S. Attorney General Eric Holder, among others. In the hacker world,
the practice is known as "doxing."

An FBI spokeswoman confirmed the agency is investigating the breach. All
told, hackers released information on 20 people, but credit reports were
not available for every victim.

Some of the personal data included credit reports from TransUnion,
Experian and Equifax, the three main U.S. credit-rating agencies.
Equifax spokesman Tim Klein said the source for the credit reports
appears to be "Annualcreditreport.com" and not the result of a breach of
the credit reporting agencies' databases.
